(CHANGELOG_HISTORY_INDEX_MAX, CHANGELOG_N, gen_origin): New vars. (ChangeLog, unchanged-history-files, change-history) (change-history-commit): New rules. * admin/admin.el (make-manuals-dist--1): Don't worry about doc/ChangeLog. * admin/authors.el: Add a FIXME. * admin/make-tarball.txt: * lisp/calendar/icalendar.el: * lisp/gnus/deuglify.el: * lisp/obsolete/gulp.el: * lwlib/README: Adjust to renamed ChangeLog history files. * admin/merge-gnulib (GNULIB_MODULES): Add gitlog-to-changelog. * admin/notes/repo: Call it 'master' a la Git, not 'trunk' a la Bzr. Remove obsolete discussion of merging ChangeLog files. New section "Maintaining ChangeLog history". * build-aux/git-hooks/pre-commit: Reject attempts to commit files named 'ChangeLog'. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * make-dist: Make and distribute top-level ChangeLog if there's a .git directory.
